"It's absurd," he told reporters, according to The National Journal. "No, we're not pretending it's anybody, but shooting pistols. It's a very terrible and horrible remark and I'm glad I didn't hear it."

The Journal adds that the Secret Service "said it would look into whether the incident posed a legitimate threat."
